IMPROVEMENT IN SOLE-PRESSING MACHlNES.

Specification forming part of Letters Patent No. 139,577, dated June 3,1873; application tiled May 6, 1873.

' of my invention sufficient to enable those skilled in the art topractice it.

`The invention relates particularly to an or` ganization ofthe machineby which the operator, in placing soles to be formed by the pressuremechanism, is not brought into such proximit-y to the press as toendanger the hands. For this purpose I use, in connection with avertically-operating mold or dieplate, a llorizontal wheel, upon whichare placed four, or any other suitable number, of bedplates, against ortoward each of which, in turn, the die plate or platen moves to compressand shape th-e sole laid upon it. This wheel has an automaticintermittent rotative movement in conjunction with the automatic'intermittent downward movement of the platen, and while the wheelis atrest for the descent of theplaten the outer plate of the wheel is inposition for the attendant to place thereon a sole.

It is in the organization thus generally described that the inventionprimarily consists.

The drawing represents a machine embodying the invention.

Figure l shows the machine in side elevation. Figif is a plan ot' it.Fig. 3 is an end view.

a denotes a stand or frame having side bearings b, in which slidevertical rods c, said rods having tixed to their tops a cross-head, d.to which the die plate or blockeis fixed, acrossbar, f, connecting thelower ends of the rods. To the bar f and to the `bottom 'of the top beamg of the frame a the outer ends ot' toggles h are jointed, the innerends of said toggies being jointed together and to a link, i, thatconnects them with a crank, lo, on a shaft,

l, which shaft may be driven by any suitable means, the rotation of thecrank effecting the just above this Wheel is a collar having au arm, 1',to which is jointed a pawl, s, the arm being connected by a link, t,with a crankarm, u, on the end of the shaftl. As the dieblock e descendsthe shaft throws 'back the arm r and the wheel is held stationary whilethe die-block presses into form the sole laid upon the plate p beneaththe die-block, and asA the die-block rises the arm r is driven forwardand turns the wheel sufficiently to bring the next platebeneath thedie-block.

By the movements of the wheel "the attendant has always before him theoutermost plate for placing the sole thereon, and has no occasion everto introduce the hand under the platen, and by the position of thesolereceiving plate he is enabled t0 place the sole more accurately forthe action of the die-block than when he has to guard his hands frombeing taken by the descending platen. For this reason the machine may berun much more rapidly and efficiently than when made in the ordinarymanner.

In a machine for pressing the soles of boots and shoes, I claim- Incombination with the vertically-reciprocating pattern or die-block e theintermittentlyrotating wheel o with its die-plates p, operatingsubstantially as shown and described.
